Answer:
The missing reactant is 55/25Mn
Explanation:
asumming the missing reagent is A/Z X
In nuclear reaction , the sum of atomic number and mass number of on both sides musst be equal
Thus ,
Z + 54 = 79 + 0
Z = 25
The element with atomic number 25 is Mn
A + 143 = 197 +1
A = 55
Therefore, the missing reagent is 55/25Mn
Then the earth would most likely not be able to support life. Our earth would be similar to mars. In that it might have supported life. It the thin atmosphere would over all be unable to sustain more complex species. The earth would also be much colder because the green house effect is what maintains our relatively warm atmosphere.
Answer:
Explanation: In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound. The subscripts that follow each element's symbol indicate how many of that element are in the compound. Notice how H is located in more than one place.
Explanation:
Answer:
The answer is
<h2>800 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 10 g/ml
volume = 80 ml
The mass of the substance is
mass = 10 × 80
We have the final answer as
<h3>800 g</h3>
