A biomedical company uses a certain type of bacteria to manufacture a new medicine. A researcher for the company studies how temperature affects the rate at which the bacteria reproduce. He records his results in a graph. mc170-1

Currently, the company grows the bacteria in a lab maintained at 18 °C. If the company wants to grow the bacteria as quickly as possible, which recommendation should the researcher make?

The current lab temperature is ideal for growing the bacteria.

The lab temperature should be increased to between 20 °C and 30 °C.

The lab temperature should be increased to between 30 °C and 40 °C.

The lab temperature should be increased to between 40 °C and 50 °C.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

did anyone actually do this? like if anyone has submitted this i rly need .

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
