Answer:
13g
Explanation:
The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction.
Therefore, if the total mass of the products is 30g, that means that the reactants have a mass of 17g + the other reactant to = 30g.
30g - 17g = 13g
<span>Carbonic acid is a chemical compound with the chemical formula H₂CO₃. It is also a name sometimes given to solutions of carbon dioxide as it contains water. It affects the rock by a process. When water meets carbon-dioxide in the air, a weak solution occurs called "CARBONIC ACID" and when it meets the crack of the rock, it diffuses and it ti dissolve with it. HOPED THIS HELPS YOU :)</span>
Answer:
T=34.20 °C
Explanation:
The formula given by the problem is
ρ= 1.5794 - 1.836*10⁻³ *(T-15)
ρ is density (in g/mL), and T is temperature (in °C).
To solve the problem we use a ρ of 1.543 g/mL and solve the equation for T:
1.543 = 1.5794 - 1.836*10⁻³ *(T-15)
0.0364 = 1.836*10⁻³ *(T-15)
19.1983=T-15
T=34.20 °C
Single and double replacement chemical reactions are similar by the fact that in both the types of reactions replacement of ions takes place in case of single displacement it is 1 ion while for double displacement it is 2 ions.
<h3>What are chemical reactions?</h3>
Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.
There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction, there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical reactions:
1) inorganic reactions
2)organic reactions
3) biochemical reactions
During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
