why does his apple tastes less sour after 15 days
Answer:
Maybe because that he ate the apple when it wasn't ready or fully grown yet just like bannans if bannanas are green that means that they are still growing so maybe that why it tasted sour or prob because he ate an green apple because thos apples are sour.

Can you help me please
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.

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
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
The mass of 0.10 mole of methane
Answer:
A methane molecule is made from one carbon atom and four hydrogen atoms. Carbon has a mass of 12.011 u and hydrogen has a mass of 1.008 u. This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams.

The mass of 0.10 mole of methane (CH4) is 1.6grams.
HOW TO CALCULATE MASS?The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;
mass = moles × molar mass
According to this question, there are 0.10 mole in methane (CH4). The molar mass of CH4 is 16g/mol.
Mass of CH4 = 0.10 × 16
Mass of methane = 1.6grams.
Therefore, the mass of 0.10 mole of methane (CH4) is 1.6grams.

Explanation:
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
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.

A sample of gas is kept at a temperature of 300 k, a volume of 1.45L, and a pressure of 3.00 kPa. How many moles of has are in the sample
Answer:
the number of moles of the gas is 0.00174 mol.
Explanation:
Given;
temperature of the, T = 300 K
volume of the gas, V = 1.45 L
Pressure of the gas, P = 3.0 kPa
The number of moles of the gas is calculated using Ideal gas equation, as follows;
PV = nRT
Where;
n is number of moles of the gas
R is the ideal gas constant, = 8.315 L.kPa/mol.K
n = PV / RT
n = (3 x 1.45) / (8.315 x 300)
n = 0.00174 mol.
Therefore, the number of moles of the gas is 0.00174 mol.

Which of the following is deforestation most likely to cause?
A.
an increase in the amount of soil on Earth
В.
an increase in the amount of minerals on Earth
C.
an increase in the amount of carbon dioxide in Earth's atmosphere
D
an increase in the amount of ozone in Earth's atmosphere
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
How many moles do I have of Lithium if I have 116.3g
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.

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!
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
