I think the correct answer from the choices listed above is option B. The list which includes three type of chemical reactions would be decomposition, single replacement, and double replacement. These are the most basic reactions in chemistry and are the basis for other types of reactions.
It’s b . The magnesium will dissolve and the copper will be deposited
Answer:
Then pressure will double
Explanation:
PV = nRT
P = nRT / V
If all other variables are kept constant, P will be proportional to n i.e
P1 / n1 = P2 / n2
n = 1
P1 = P
n2 = 2
P2 =?
P1 / n1 = P2 / n2
P /1 = P2/2
Cross multiply
P2 = 2P
Therefore, if an additional 1mole of the gas is added, the pressure will double
Answer:
The answer to your question is: 2Mg + O₂ ⇒ 2MgO
Explanation:
Data
Magnesium = Mg
Oxygen = O
Equation
2Mg + O₂ ⇒ 2MgO
Reactants Products
2 -------- Mg ---------- 2
2 -------- O --------- 2
A young river has very few tributaries and flows quickly. It's channels erode deeper rather than water. So, the answer is A.
