<h3>What is a Chemical reaction?</h3>
This is the reaction which involves substances known as reactants combining new substances which are referred to as products. This is usually done in the laboratory and equipment and tools such as test tubes, thermometer etc are used.
Test tubes, spot and/or well plate are often used to combine substances in bottles and form a reaction which must be handled with care to ensure it doesn't spill.
This is therefore the reason why the option true was chosen as the most appropriate choice.

Answer;
Taxes
A disadvantage of corporations is that shareholders have to pay taxes on profits.
Explanation;
A corporation or public corporation is a form of business unit that is a legal entity, which in usually organized under the laws of a state, and whose investors or share holders purchase shares of stock as evidence of ownership in it.
One of the disadvantages of corporation is double taxation; A corporation may pay taxes on its income, after which the investors or the shareholders pay taxes on dividends earned, and therefore it means the income has been taxed twice.
Answer:
61.3 g/mol
Step-by-step explanation:
We can use the <em>Ideal Gas Law</em> to solve this problem:
pV = nRT
Since n = m/M, the equation becomes
pV = (m/M)RT Multiply each side by M
pVM = RT Divide each side by RT
M = (mRT)/(pV)
<em>Data:
</em>
m = 0.675 g
R = 0.0.083 14 bar·L·K⁻¹mol⁻¹
T = 0 °C = 273.15 K
p = 1 bar
V = 250 mL = 0.250 L
<em>Calculation:
</em>
M= (0.675 × 0.083 14 × 273.15)/(1 × 0.250)
M= 15.33/0.250
M= 61.3 g/mol

Answer:
The concentration of sulfuric acid in the flask is 
Explanation:
The number of moles is mathematically defined as
For the number of moles of NaOH substituting 15.0mL = 
for volume and 0.25M for concentration we have
From the balanced equation we can that the number of moles of 
required for this reaction is
Concentration is mathematically defined as
Concentration of
