Answer:

acetyl-CoA.

Explanation:

Fatty acids are broken down into acetyl-CoA by the process of beta-oxidation inside the mitochondrial matrix part of the powerhouse of the cell. Whereas fatty acids are synthesized from acetyl-CoA in the mitochondria.

Then acetyl-CoA which is produced by beta-oxidation enters the citric acid cycle in the mitochondrion by combining with oxaloacetate to form citrate and then complete the combustion of the acetyl-CoA into carbon dioxide and water.

WHAT MASS OF WATER WILL BE PRODUCED FROM 2.70 MOLES OF CA(OH)2 REACTING WITH HCI

Keith_Richards [23]

Answer: The mass of water produced in the reaction is 97.2 grams

Explanation:

We are given:

Moles of calcium hydroxide = 2.70 moles

The chemical equation for the reaction of calcium hydroxide and HCl follows:

$Ca(OH)_2+HCl\rightarrow CaCl_2+2H_2O$

By Stoichiometry of the reaction:

1 mole of calcium hydroxide produces 2 moles of water

So, 2.70 moles of calcium hydroxide will produce = $\frac{2}{1}\times 2.70=5.40mol$ of HCl

To calculate mass for given number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Molar mass of water = 18 g/mol

Moles of water = 5.40 moles

Putting values in above equation, we get:

$5.40mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=(5.40mol\times 18g/mol)=97.2g$

Hence, the mass of water produced in the reaction is 97.2 grams

You have 16.6 g of water at 40.2 C. How many Joules are needed to warm the water to 44.8 C?

iragen [17]

Answer:

Q = 319.49 J

Explanation:

Given that,

Mass, m = 16.6 g

Initial temperature, $T_i=40.2^{\circ} C$

We need to find the heat needed to warm the water to 44.8 °C. The formula that is used to find the heat required is given by :

$Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\Q=16.6\ g\times 4.184\ J/g^{\circ} C\times (44.8-40.2)^{\circ} C\\\\Q=319.49\ J$

So, 319.49 J of heat is needed to warm water.

Why do atoms always contain the same number of electrons and protons?

katovenus [111]

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.

What is the first step in nuclear fission? 60 POINTS BRAINLIEST

kobusy [5.1K]

Answer:

Energy is released. In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy.
