We are going to use this formula:
Q = M*C*ΔT
when Q is the heat required
M is the mass of CCl4 = 10.35 g
C is the specific heat capacity of CCl4 = 0.874J/g.c
and ΔT the change in temperature = 56.4 - 32.1 °C =24.3 °C
∴ Q = 10.35g * 0.874 * 24.3 °C
= 219.8 J
2 O2 + CH4 CO2 + 2 H2O
<span>What mass of CH4 is required to completely react with 100 grams of O2? </span>
<span>mass CH4 = 100 g O2 x (1 mol O2 / 32 g) x (1 mol CH4 / 2 mol O2) x (16.05 g / 1 mol CH4) </span>
<span> 25 grams CH4

Answer:
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
Answer:anions have a negative charge and cations have a positive charge therefor they can form ionic bonds
Explanation:
The three elements that make up over 99 percent of organic molecules are carbon, hydrogen and oxygen. These three combine together to form almost all chemical structures needed for life, including carbohydrates, lipids and proteins.
