Which of these statements explains the relationship among elements, compounds, and mixtures?
gladu [14]
A compound is where two or more elements have chemically bonded, and a mixture is where there are two or more elements are grouped together, but they are not chemically bonded.
An example of a mixture would be salt dissolved in water, and an example of a compound would be water (which is made up of 2 Hydrogen and 1 Oxygen bonded together)

tl;dr: I would go with B, basically.

Calculate the volume of 0.100 m hcl required to neutralize 1.00 g of ba(oh)2 (molar mass = 171.3 g/mol).
dedylja [7]

The balanced chemical equation between HCl and Ba(OH)_{2} is:

2HCl (aq) + Ba(OH)_{2}(aq) -->BaCl_{2}(aq) + 2 H_{2}O(l)

Moles of Ba(OH)_{2} = 1.00 g Ba(OH)_{2} * \frac{1 mol Ba(OH)_{2}}{171.3 g Ba(OH)_{2}} = 0.00584 mol Ba(OH)_{2}

Moles of HCl required to neutralize Ba(OH)_{2}:

0.00584 mol Ba(OH)_{2} * \frac{ 2 mol HCl}{1 mol Ba(OH)_{2}} =   0.01168 mol HCl

Calculating the volume of HCl from moles and molarity:

0.01168 mol HCl * \frac{1 L}{0.100 mol} * \frac{1000 mL}{1 L} = 116.8 mL

If you burn 23.4 g of hydrogen and produce 209 g of water, how much oxygen reacted?
Kitty [74]
The chemical reaction is expressed as:

2H2 + O2 = 2H2O

To determine the amount of oxygen used in the reaction, we use the amount of water produced and the relation of the substances in the reaction we do as follows:

209 g H2O ( 1 mol / 18.02 g ) ( 1 mol O2  / 2 mol H2O ) ( 32 g / 1 mol ) = 185.57 g O2
