Answer:

4.both beneficial and harmful

Explanation:

Mutations that occur in bacteria that make them immune to antibiotic action can be a beneficial or harmful mutation, it depends on whether you are referring to the bacteria or to humans.

The mutation is beneficial to the bacterium because with the mutation it becomes immune to the antibiotic reaction, achieves resistance and becomes an "unbeatable" bacterium, so the mutation has a huge benefit for the bacterium because it allows it to survive and continue its life. metabolism normally.  

On the other hand, this mutation is extremely harmful to humans, because the antibiotic is what we have to fight bacteria and get rid of infections that can cause us many problems. For this reason, the mutation that makes bacteria resistant to antibiotics is highly harmful to humans.

1. If we used 0.0100 moles of K2CO3, how many moles of SrCO3 can be expected to form?​
faltersainse [42]

Answer:

0.01 moles of SrCO₃

Explanation:

In this excersise we need to propose the reaction:

K₂CO₃ + Sr(NO₃)₂  →  2KNO₃ + SrCO₃

As we only have data about the potassium carbonate  we assume the strontium nitrite as the excess reactant.

1 mol of K₂CO₃ react to 1 mol of Sr(NO₃)₂ in order to produce 2 moles of potassium nitrite and 1 mol of strontium carbonate.

Ratio is 1:1. In conclussion,

0.01 mol of K₂CO₃ must produce 0.01 moles of SrCO₃

A 80.0 g piece of metal at 88.0°C is placed in 125 g of water at 20.0°C contained in a calorimeter. The metal and water come to
grandymaker [24]

Answer:

The specific heat of the metal is 0.485 J/g°C

Explanation:

<u>Step 1:</u> Data given

Mass of the piece of metal = 80.0 grams

Mass of the water = 125 grams

Initial temperature of the metal = 88.0 °C

Initial temperature of water =20.0 °C

Final temperature = 24.7 °C

pecific heat of water is 4.18 J/g*°C

<u>Step 2:</u> Calculate specific heat of the metal

Qgained = -Qlost

Q =m*c*ΔT

Qwater = - Qmetal

m(water)*c(water)*ΔT(water) = -m(metal)*c(metal)*ΔT(metal)

with mass of water = 125 grams

with c( water) = 4.18 J/g°C

with ΔT(water) = T2-T1 = 24.7 - 20 = 4.7°C

with mass of metal = 80.0 grams

with c(metal) = TO BE DETERMINED

with ΔT(metal) = 24.7 - 88.0 = -63.3 °C

125*4.18*4.7 = -80 * C(metal) * -63.3

2455.75 = -80 * C(metal) * -63.3

C(metal) = 2455.75 / (-80*-63.3)

C(metal) = 0.485 J/g°C

The specific heat of the metal is 0.485 J/g°C
