Answer is: 2H, 1S, 4O, 1Ba, 2Cl or 2,1,4,1,2.
Number of atoms must

</span>There are two hydrogen atoms, one sulfur atom, four oxygen atoms, one barium atom and two chlorine atoms in this chemical reaction.
Answer:
86% is the percent yield of the reaction
Explanation:
Percent yield is defined as 100 times the ratio of actual yield / theoretical yield.
Based on the reaction:
2Na + Cl₂ → 2NaCl
The theoretical yield is 0.50 moles because 0.50 mol of Na are added in the beginning. As 0.43 moles are produced, actual yield is 0.43 mol. And percent yield is:
0.43mol / 0.50mol * 100 =
<h3>86% is the percent yield of the reaction</h3>
Answer:
an inducer
Explanation:
An Enzyme is a protein molecule found in cells which work as biological catalysts.
They speed up chemical reactions in the body, but do not get used up in the process, and can be used over and over again.
In chemistry inducers are molecules that regulates gene expression, and can bind to protein repressors or activators.
Lactose here acts as an inducer because it inactivates the repressor of an operon.
Averqge speed of the car = 45 miles/hr, which means,
The car travels 45 miles in 1 hr.
Using unitary method,
The car travels 45 miles in 1 hr
The car would travel 1 mile in 1/45 hrs
The car would travel 90 miles in 1/45×90 hrs
So, calculating this,
1/45×90 = 2 hrs
