Answer:

The correct answer is 29 grams.

Explanation:

Based on the given question, the reaction will be,

CH3CH=CHCH3 + H2 ⇒ CH3CH2CH2CH3

The molecular weight of butene is 56 grams per mole, and the molecular weight of butane is 58 grams per mole.

Thus, it can be said that 56 grams of butene reacts with hydrogen gas and produces 58 grams of butane.

Therefore, 28 grams of butene when reacts with hydrogen gas to give,

= 58/56 * 28 = 29 grams of butane.

Hence, the mass of butane produced will be 29 grams.

How many Na ions are in 2.7 g of NaCl?<br> Answer in units of ions.

Viefleur [7K]

Answer:

$2.778 * 10^{22}$

Explanation:

Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.

Mathematically, it can be represented as -

1 mol (Na) $+$ 1 mol (Cl) $= 23.0 + 35.5 = 58.5$ g/mol

In $58.5$ gram of NaCl, there is one mole of Na or $6.02 * 10^{23}$ ions

In one gram of NaCl, there will be

$\frac{6.02 * 10^{23}}{58.5}$ sodium ions

In $2.7$ grams of NaCl, the number of sodium ions will be -

$\frac{6.02 * 10^{23}}{58.5} * 2.7$

$2.778 * 10^{22}$

Does the energy go from the surrounding to the chemicals or from the chemicals to the surround in an exothermic reaction?

Karo-lina-s [1.5K]

In general terms, exothermic reactions release energy, so the energy goes from the system to the surroundings.
