A 25.0 mL sample of HCI reacted with 20.0 mL of 2.00 M NaOH. What is the molarity of the HCI?
HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)
really need help!

Answers

Answer:

Molarity of HCl = 1.6M

Explanation:

The chemical reaction equation is;

HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)

Now, molarity = number of moles/volume

Thus, for NaOH, we have;

Number of moles = molarity × volume = 2M × (20/1000) L

Number of moles = 0.04 moles

Using the coefficients in the chemical equation above, we can find the corresponding number of moles for HCl.

Number of moles of HCl = 0.04 moles NaOH × (1 mole of HCl/1 mole of HCl) = 0.04 moles of HCl

Thus;

Molarity of HCl = 0.04/(25/1000)

Molarity of HCl = 1.6M

How do i calculate speed and find the direction of a moving object

Answers

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

The direction of a moving object is the direction the velocity vector points in. Where v1/2 is the magnitude of the velocity halfway to the top of the trajectory. So vdown=−vup - the two velocity vectors point in opposite directions not the same direction.

Answer:

11.5 or 11.52, depending on however many decimal places you round it to

Explanation:

the equation for mass ( using the specific heat capacity equation) is energy transferred divided by temperature change x the specific heat capacity.

so, we do 725 ÷ 32° (the temp change) x 2.03 = 11.52 or 11.5, depending on how many decimal places you round to

i would round to 2 decimal places, so the answer would be 11.52kg.

mass is measured in kg :) hope this helped.

A 1.26 g sample of He gas has a pressure of 0.123 arm and a volume of 32.6 L. What is the temperature of the sample, in degrees Celsius

Answers

Hello, the answer would be -118*C

A 1.26 g sample of He gas has a pressure of 0.123 arm and a volume of 32.6 L, then the temperature of the gas is -117.7 degree C.

How do we calculate the temperature of gas?

Temperature of any gas will be calculated by using the ideal gas equation as:

PV = nRT, where

P = pressure of gas = 0.123 atm

V = volume of gas = 32.6 L

R = universal gas constant = 0.082 L.atm / K.mol

T = temperature of gas = ?

n is moles of He gas and will be calculated as:

n = W/M, where

W = given mass = 1.26g

M = molar mass = 4 g/mol

n = 1.26 / 4 = 0.315 moles

On putting values we get,

T = (0.123)(32.6) / (0.315)(0.082)

T = 155.41 K = 155.41 - 273.15 = -117.7 degree C

Hence required temperature of the helium sample is -117.7 degree C.

How many moles do I have of Lithium if I have 116.3g

Answers

Answer:

16.85mol

Explanation:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molecular mass. That is;

number of moles (n) = mass (m) /molar mass (MM)

Molar mass of lithium = 6.9g/mol

Hence,

number of moles = 116.3 ÷ 6.9

Moles = 16.85mol

Therefore, 16.85moles is present in 116.3g of Li.

C.

D
an increase in the amount of ozone in Earth's atmosphere

Answers

Answer:

C

Explanation:

trees (as well as other plants) produce carbon dioxide. deforestation is the removal of trees. this will not cause an increase in any pollutants such as ozone. ozone is made from VOCs and other harmful pollutants, and not caused by trees. tearing down trees will also not create more soil. So the answer has to be C

The boiling temperature of water is directly related to the atmospheric pressure. At sea level, the atmospheric pressure is 760 torr whereas the boiling temperature is 100equationC. If the atmospheric pressure is lower than 760 torr, then the boiling temperature will be less than 100equationC. If the atmospheric pressure is higher than 760 torr, then you would expect the boiling temperature to be higher than 100equationC. At higher elevations, the atmospheric pressure is lower resulting in a lower boiling temperature. For example: Denver, CO experiences a boiling temperature at ~ 94equationC. If you were conducting an experiment that involved boiling water, what would you expect the boiling temperature to be if the atmospheric pressure was 790 torr

Answers

Answer:

If the atmospheric pressure is lower than 760 torr, then the boiling temperature will be less than 100equationC.

B. 97.7°C

Explanation:

The question mentions the fact that temperature and pressure are directly proportional. This means that if one quantity is increasing the other increases simultaneously and vice versa.

Hence, if the atmospheric pressure is lower than 760 torr, then the boiling temperature will be less than 100equationC.

From;

PαT

P=kT

Hence

P/T = k

P1/T1 = P2/T2

P1T2 = P2T1

P1 =  760 torr

T1 = 94°C

T2 = ?

P2 = 790 torr

T2 =  P2T1/P1

T2 = 790 * 94/760

T2 = 97.7°C
