Answer:

Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration.

How many grams in 6.20 x 10^25 atoms of bromine (Br) ? image attached , will give brainliest

Deffense [45]

Answer:

8239.2g

Explanation:

Given parameters:

Number of atoms in Br = 6.2 x 10²⁵atoms

Unknown:

Mass of Br = ?

Solution:

From mole concepts, we know that:

1 mole of a substance contains 6.02 x 10²³ atoms/mol

Molar mass of Br = 80g/mol

6.2 x 10²⁵atoms x $\frac{1}{6.02 x 10^{23} }$ $\frac{mol}{atoms}$ x 80 x $\frac{g}{moles}$

= 8239.2g

How do cows contribute to the production of greenhouse gases?

miss Akunina [59]

Answer:

Cattle produce a lot of methane gas, primarily through enteric fermentation and fermentation of their manure. Methane is a powerful greenhouse gas that, along with nitrous oxide, carbon dioxide, and some other compounds in the atmosphere, create a blanket around our planet.

If E=mc^2,solve for both m and c. Also, if m=80 and c=0.40 what is the value of E?

Pie

Answer:

$m = \frac{E}{c^2}$

$c = \sqrt{\frac{E}{m} }$

$E = 12.8 J$

Explanation:

Part 1: Solving for m

We are given that:

E = mc²

To solve for m, we will need to isolate the m on one side of the equation

This means that we will simply divide both sides by c²

$m = \frac{E}{c^2}$

Part 2: Solving for c

We are given that:

E = mc²

To solve for c, we will need to isolate the m on one side of the equation

This means that first we will divide both sides by m and then take square root for both sides to get the value of c

$c^2 = \frac{E}{m}\\ \\ c=\sqrt{\frac{E}{m}}$

Part 3: Solving for E

We are given that:

m = 80 and c = 0.4

To get the value of E, we will simply substitute in the given equation:

E = mc²

E = (80) × (0.4)²

E = 12.8 J

Hope this helps :)

Draw a mechanism for the first step of the reaction between methyllithium (CH3Li) and acetone. Then answer the two multiple choi

pogonyaev

Answer:

See the attached image

Explanation:

The first step is the production of the carboanion in the $CH_3Li$ compound. We will get the negative charge on the methyl group and the positive charge in the Li atom.

Then the carboanion can attack the acetone. The double bond of the oxo group would delocalized upon the oxygen, generating a positive charge in the carbon that can be attacked by the carboanion formaiting a new C-C bond.
