How many glucose molecules can be produced per second in a plant

Masja [62]

Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule

What does it mean to optimize a solution ? How are solutions optimize

Romashka [77]

Question

What does it mean to optimize a solution?

To find out best possible solution for a given problem within the given constraint is generally termed as optimization

How are solution optimize ?

To solve an optimization problem, begin by drawing a picture and introducing variables. Find an equation relating the variables. Find a function of one variable to describe the quantity that is to be minimized or maximized. Look for critical points to locate local extrema.

This is the chemical formula for talc Mg3(Si2O5)2(OH)2(the main ingredient in talcum powder):

Elena-2011 [213]

Answer:

0.022 mol O

Explanation:

Mg3(Si2O5)2(OH)2

We can see that 1 mol of this substance has 3 mol of Mg.

Oxygen altogether is 5*2 (from (Si2O5)2) + 2(from(OH)2) = 10 +2 = 12

So, 1 mol of this substance has 12 mol oxygen.

So, 1 mol of this substance contains 3 mol Mg and 12 mol O, or

ratio Mg : O = 3 : 12 = 1 : 4

1 mol Mg ----- 4 mol O

0.055 mol Mg ---x mol O

x = 0.055*4/1 = 0.220 mol O

What is the covalent bonding of calcium chloride

algol13

Answer:

Calcium chloride does not have a covalent bond , it is an ionic bond (which means donation of electrons takes place ). The charge of calcium ions is +2, while the charge of sodium ions is -1. The molecule of calcium chloride contains one calcium ion (+2) and two chloride ions (-1), resulting in an overall charge of 0, or neutral.

IONIC BONDING IN CALCIUM CHLORIDE $(CaCl_2)$

Electron sharing produces covalent compounds, while electron donation produces ionic compounds. $CaCl_2$ is a salt with an ionic bond. This is because calcium takes up an electron to each of the chlorine atoms, resulting in $Ca^2^+$ ions for calcium and $Cl^-$ ions for chlorine. At room temperature, it behaves like a normal ionic halide and is solid. Calcium is a metal with a non-metal sulphate bond.

Thus , Calcium chloride have ionic bonds present on them . No covalent bonds takes place in calcium chloride.
