Answer : The balanced chemical reaction will be:
Explanation :
As per question when copper(II) oxide react with sulfuric acid then it gives copper(II) sulfate and water.
This reaction is known as double displacement reaction in which cation of two reactants exchange their places to give two different products.
The balanced chemical reaction will be:
Answer:
Explanation:
Hello,
In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:
Next, we compute the final pressure P2:
Thus we validate, the higher the volume the lower the pressure.
Best regards.
Answer:
Role of photosynthesis
It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process.
Explanation:
The answer is D. This is because you can observe that gravity pulls things downward, it is not contradicted by data and we are always continuing to experiment with the laws of science.
:
<span> Molar mass of NaCl: 35.4+22.9 = 58.3 g/mol
X milliliters (=X/1000 liters) of a 0.171M solution contain 0.171*X/1000 moles of NaCl.
0.171*X/1000 moles of NaCl = 58.3*0.171*X/1000 g = 1 g (as given)
58.3*0.171*X/1000 = 1
X = 100.3 </span>
