The metal that does not form cations of differing charges is Sodium (Na).
The transition metals refers to the group of metals which one can find in the middle of a periodic table. Some of the metals that are able to form cations with different charges include:
It should be noted that Sodium (Na) is a metal metal that does not form cations of differing charges.
Therefore, the correct option is A.

Answer:
6m
Explanation:
For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
Answer:
69.036 g of Compound is required to obtain 48.45 g of Oxygen.
Explanation:
Let us assume that the total mass of the compound is 100 g. So it means that this compound weighing 100 is composed 70.18 % of Oxygen or among 100 g of this compound 70.18 g is constituted by oxygen only. Hence, we can make a relation as that,
70.18 g O is present in = 100 g of a Compound
So,
48.45 g of O will be present in = X g of a Compound
Solving for X,
X = 100 g × 48.45 g ÷ 70.18 g
X = 69.036 g of Compound
Answer:
The exosphere
Explanation:
In Earth atmosphere, the closer to the ground is the troposphere, then the stratosphere, then the mesosphere, in which the highest clouds and radar can reach. Then in the thermosphere, where the auroras and the satellites are form, the air glow starts to disappear until we reach the space in the last layer called exosphere.
Answer: C3H4 (Propayne) have a triple bond.
Explanation:
The hydrocarbons which having triple bond are called alkyne. The general formula of alkyne is CnH2n-2. Here, n is number of carbon atoms.
In alkyne, the number of hydrogen atom is 2 less than double the number of carbon atoms.
Thus, the compound C3H4 (Propyne) have a triple bond.
