Answer:
Most similar - Lithium
Least similar - Phosphorus
Explanation:
Rubidium is an element in group 1A of the periodic table. It is a metal and forms an ionic compound with chlorine. The formula of the compound is RbCl.
If we look at the options, Lithium is also a group 1A element and forms an ionic compound with chlorine having the formula LiCl which is very much similar to RbCl chemically.
Phosphorus is a nonmetal. Its compounds with chlorine, PCl3 and PCl5 are covalent and does not resemble RbCl in any way.
Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
![C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O](https://tex.z-dn.net/?f=C_6H_%7B12%7DO_6%2B6O_2%5Crightarrow%206CO_2%2B6H_2O)
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of
= Total mass of ![6CO_2+6H_2O](https://tex.z-dn.net/?f=6CO_2%2B6H_2O)
As we are given :
Total mass of
= 65.7 grams
So,
65.7 grams = Total mass of ![6CO_2+6H_2O](https://tex.z-dn.net/?f=6CO_2%2B6H_2O)
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
The magnitude of the force causing this acceleration is 15 N
<u>Explanation:</u>
we know that
F=ma: According to the newton's second law
F - force acting on the object
m - mass of the object
a - acceleration
Newton's second law states that acceleration depends on force acting on the object and mass of the object.
Force is directly proportional to acceleration and mass is inversely proportional to acceleration.
here,
m = 5 kg
a = 3 m/s2
![F = m \times a\\F = 5 \times 3\\F = 15 N](https://tex.z-dn.net/?f=F%20%3D%20m%20%5Ctimes%20a%5C%5CF%20%3D%205%20%5Ctimes%203%5C%5CF%20%3D%2015%20N)
Nucleus - controls and regulates the activities of the cell
nucleolus - producing and assembling the cells ribosome
nuclear membrane - separate the chromosomes from the rest of the cell
chromosomes - carries genetic information from one generation to another
ribosome - making proteins
cytoplasm - responsible for holding the components of the cell and protects them from damage, stores the molecules required for cellular processes and is also responsible for giving the cell its shape
cell membrane - provides protection for a cell, transport nutrients into the cell and also to transport toxic substances out of the cell
mitochondria - membrane-bound cell organelles that generate most of the chemical energy needed to power the cells biochemical reactions
Golgi complex - responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations
vacuole - (animal cells - help sequester waste products ) ( plant cells - help maintain water balance)
endoplasmic reticulum- produce proteins for the rest of the cell to function
cell wall - surrounds the plasma membrane of the plant cells and provides tensile strength and protection against mechanical and osmotic stress
chloroplast - allow plants to capture the energy of the sun in energy-rich molecules
