Answer:

They are decomposers, eating dead plant material and organic waste. By doing this, the bacteria release nutrients that other organisms could not access. The bacteria do this by changing the nutrients from inaccessible to usable forms. The process is essential in the nitrogen cycle.

Explanation:

Most are decomposers that consume simple carbon compounds, such as root exudates and fresh plant litter. By this process, bacteria convert energy in soil organic matter into forms useful to the rest of the organisms in the soil food web. A number of decomposers can break down pesticides and pollutants in soil.

Answer:

Covalent so it is C.

Explanation:

That is water bro.

H2O and water is covalent since they are shared and they are touching in the picture.

Electrons are being shared not transferred and covalent means they are being shared.

Hope this helps!

Suppose a sodium hydroxide solution was standardized against pure solid primary standard grade KHP. If 0.4798 g of KHP required

Readme [11.4K]

Answer:

The NaOH solution has a molarity of 0.052 M

Explanation:

Step 1: Data given

Mass of KHP = 0.4798 grams

Volume of NaOH= 45.22 mL = 0.04522 L

Molar mass of NaOH = 40 g/mol

Molar mass of KHP = 204.22 g/mol

Step 2: Calculate moles of KHP

Moles KHP = mass KHP / Molar mass KHP

Moles KHP = 0.4798 grams / 204.22 g/mol

Moles KHP = 0.00235 moles

Step 3: Calculate moles of NaOH

KHP here acts as a mono-acid so, the number of moles of NaOH = number of moles KHP = 0.00235 moles

Step 4: Calculate molarity of NaOH

Molarity NaOH = moles NaOH / volume NaOH

Molarity NaOH = 0.00235 moles / 0.04522 L

Molarity NaOH = 0.052 M

The NaOH solution has a molarity of 0.052 M

What is the percent by mass of oxygen in carbon dioxide (CO2)? Use mc008-1. Jpg. 27. 29% 57. 12% 72. 71% 79. 99%.

castortr0y [4]

The percent by mass of oxygen in carbon dioxide ( $CO_2$ ) is 72.71%.

Scientific data:

Molar mass of oxygen gas = 32 g/mol.

Molar mass of carbon = 12 g/mol.

To calculate the percent by mass of oxygen in carbon dioxide ( $CO_2$ ):

First of all, we would calculate the molar mass of carbon dioxide ( $CO_2$ );

$CO_2 = 12 +(16\times 2)\\\\CO_2 = 12 +32\\\\CO_2 = 44\;g/mol$

For the percent by mass of oxygen:

$O_2 = \frac{Mass\; of \;O_2}{Mass\; of \;CO_2} \times 100$

Substituting the parameters into the formula, we have;

$O_2 = \frac{32}{44} \times 100\\\\O_2 = 0.7271 \times 100$

Percent mass of oxygen = 72.71%

The energy stored in molecular bonds is called _____.

makvit [3.9K]

Correct answer is chemical energy.

Reason:

For the chemical reactions to occur, energy is to be supplied for breaking and reorganization of bonds. This energy can be in form of heat, light, etc. Since, breaking of bonds results in chemical reactions to occur, the energy stored in molecular bonds is called Chemical energy.
