The class can break or if you put it in cold water it can cool down down fast.
The reaction in which two reacting molecules exchange their partner ions in aqueous solution and form two new compounds.
Answer:
false
Explanation:
cuz carbon dioxide is greenhouse gasses
Answer:
The correct answer is - 14.
Explanation:
In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:
Al = 2 atoms represented by subscript
S = 3 atoms represented as whole subscripts of sulfite
O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.
Thus, total number of atoms are 2+3+9 = 14
Answer:
D 1.0 g of powdered Zn(s) in 50. mL of 1.0 M HCl(aq) at 30.°C
Explanation:
There are several factors affecting and controlling the rate of chemical reactions.
Some of which are applicable in resolving this problem is the nature of the reactants and their concentration. Also, the temperature of the reaction is also very important.
- Reactants that powdered ensures a faster rate because, more surface area is exposed for the reaction.
- Also, the higher the temperature, the faster the reaction will take place.
- So, the powdered zinc and the higher temperature reaction will facilitate a better rate of reaction.
