Answer:
The C4+ ion has the smallest ionic radius
Explanation:
In the periodic table, the size of an atom increases on going downwards in a group.
On the other hand, in a period, size decreases on going from left to right
The size of cation is smaller than its parent atom.
Lithium-ion (Li+) is the most left so it has the biggest radius.
More to the right ( this means a smaller ionic radius) , we have Berylium-ion (Be2+).
More to the right, so smaller than Be2+, we have B3+
The ion the most to the right, we have C4+
The C4+ ion has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
Answer:
*2Kl+Pb(NO3)2=PbI2+2KNO3: double replacement.
*2Al+3CuSO4=Al2(SO4)3+3Cu: single replacement.
*C2H5OH+3O2=2CO2+3H2O: combustion.
Explanation:
Hello there!
In this case, according to the required, it turns out necessary for us to recall the five types of reactions, combination, decomposition, single and double replacement and combustion as shown on the attached figure.
In such a way, since the first reaction follows the pattern AB+CD-->AD+CB we infer it is double replacement; the second reaction follows the patter A+BC-->AC+B and therefore it is single replacement; and the last one follows the pattern of combustion reaction due to the presence of CO2 and H2O on the products side.
Regards!

Answer:</h3>
Cytokinesis in animal cells occur by cleavage while in plants it occurs through the formation of a cell plate.
<h3>
Explanation:</h3>
- Cytokinesis refers to the process through which the cytoplasm divide in animal and plant cells.
- It occurs after the division of the nucleus.
- Cytokinesis in animal cells differs from that in plant cells in that, in animal cells it occurs by cleavage while in plant cells cytokinesis occurs through the formation of a cell plate.
- In animal cells, cleavage occurs as a result of the activity of actin and myosin which results to dividing of cytoplasm in to two.
- In plant cells, cell plate is formed by the fusion of golgi bodies on the equator which will generate cell wall and the plasma membrane between daughter cells.
The answer in C. Greenhouse Gases. Greenhouse Gases is caused by the trapped heart in the atmosphere harming us which we will always have. hope this helped
