Answer: It will take 10 years for the account to double in value. Account is defined as a record in an accounting system that keeps tabs on the financial transactions involving a particular asset, obligation, equity, source of income, or expense. It is used to document financial transactions, totals, or balances related to assets, liabilities, income, outlays, and owner equity. Given future value = 2 x 5,000 = $10,000 Present value = $5,000 Interest rate = 7% n = number of periods to double in value The value of n can be calculated as FV = PV x ( 1 + r ) ⁿ 10,000 = 5,000 x ( 1 + 0.07 ) ⁿ 2 = 1.07 ⁿ n = ln ( 2 ) / ln ( 1.07 ) n = 10.24 Thus, it will take 10 years for the account to double in value.

The ratio of atoms in HCl is The ratio of atoms in hydrogen chloride shortened as HCl is 1:1. This is because there is only one atom of hydrogen that is reacted with another atom of chlorine. A ratio indicates the relative sizes of two or more quantities. When given another compound like H₂ SO₄, we can describe the elements as being in the ratio of 2:1:4. Thus, we can see the relative quantities of the individual elements in the given compound. In conclusion, the ratio of atoms in HCl is 1:1. Learn more about the ratio of atoms here:
Answer: Each molecule of HCl is composed of a one-to-one ratio of hydrogen and chlorine. Explanation: At room temperature, HCl is a colorless, poisonous gas. Dissolve it in water, and, voilà, you have hydrochloric acid. For the record, acids are substances that release hydrogen ions in water. The more hydrogen ions an acid releases in water, the stronger the acid (see "What is an ion?" below). If you concluded from the above discussion that HCl releases many hydrogen ions in water, you are right!

Answer: Mass percent of N2H4 in original gaseous mixture = 31.13 % Explanation: Given: Initial mass of gaseous mixture = 61.00 g Initial mole of oxygen = 10.0 mol Moles of oxygen remaining after the reaction = 4.062 mol Moles of oxygen used = 10.0 - 4.062 = 5.938 mol Total oxygen used in both the reactions = 10.0 parts out of 10 parts, 3 part react with N2H4. Now, consider the reaction of N2H4 3 moles of O2 react with 1 mole of N2H4 1.78 moles of oxygen will react with 1.78/3 = 0.5933 mol of N2H4 Molecular mass of N2H4 = 32 g/mol Total mass = 61.0 g
The mass percent of N2H4 in the gaseous mixture can be determined through stoichiometric calculations and determining the limiting reactant. The initial and remaining amounts of O2 are used to calculate the reacted amount of O2, which then allows for the calculation of the amount of N2H4. This information is used in the mass percent formula. The balanced reaction states that for one mole of NH3, one mole of O2 is required, while for one mole of N2H4, 3 moles of O2 are required. Thus, the initial moles of O2 were 10 moles and after reaction 4.062 moles O2 remained. Thus, the reacted amount of O2 is 10 - 4.062 = 5.938 moles. From calculating the limiting reactant and applying stoichiometry, the amount of N2H4 can be determined. We know the molar mass of N2H4 is 32 g/mole. By calculating the molar ratio, we can then calculate the mass percent of N2H4 in the mixture using the formula: (mass of N2H4 / total mass) * 100%. #SPJ12Final answer:

There are two types of conductance a) molar conductance b) specific conductance specific conductance is also known as conductivity Molar conductance [the conductance offered by one mole of electrolyte dissolved in any volume of solution] increases with increase in dilution. The reason for weak and strong electrolytes are different. i) for weak electrolytes the molar conductance increases due to increase in degree of dissociation ii) for strong electrolytes the molar conductance increases due to decrease in inter ionic interactions Conductivity (specific conductance) is the conductance offered by one unit volume of an electrolytic solution The conductivity decreases with increase in dilution due to less number of ions per unit volume of solution. so here the conductivity of resulting solution will decrease if water is added to a 0.10 M NaCl solution
The more water added the lower the conductivity. The Na+ and Cl- ions allow the solution to be conductive. The lower the concentration, the less conductive the solution will get until it is not conductive at all.

The compound that has both ionic and covalent bonding is Further Explanation: The attraction between different atoms, molecules and ions is known as a chemical bond. The formation of various types of compounds takes place as a result of these chemical bonds. An ionic bond is formed as a result of the interaction between a metal and a non-metal. Metals have the tendency to lose electrons while non-metals tend to gain electrons. Due to this, metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons. A covalent bond is formed by the mutual sharing of electrons between the bonded atoms. It is also called the molecular bond. Such bonds usually exist between two or more non-metals. (1) Its constituents are (2) It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So (3) It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So (4) It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds.

CaCO3 is the substance that contains both ionic and covalent bonds. Calcium ions (Ca2+) and carbonate ions (CO3-2) make up the salt known as CaCO3. Ionic bonds, which are created when one atom donates electrons to another atom, are what bind the calcium and carbonate ions together. Three oxygen atoms and one carbon atom, linked together by covalent bonds, make up the carbonate ion. The three oxygen atoms and the carbon atom share electrons to create a covalent connection. Atoms exchange electrons to make covalent connections, whereas atoms give away electrons to produce ionic bonds. In CaCO3, an ionic connection is created when the calcium atom donates electrons to the carbonate ion. The carbon atom shares electrons at the same moment. Learn more about covalent bonding at: #SPJ6

Answer : Option D) Double replacement Explanation : Double displacement or replacement reactions are those in which the two reactant molecules exchange the cations and anions between them and give a new product. So, in this case when the reaction is AB + CD → AD + CB Here, both the species of reactant compound molecule went replacement with the adjacent cation and anion group and formed a new compound or product. Therefore, this can be called as double replacement reaction.
Thetype of reaction is represented by the generic equation AB + CD -> AD + CB is double replacement. The restof the choices do not answer the question above.
