Answer: -
The approximate number of atoms in a bacterium is 10¹¹
Explanation: -
We are given the mass of a bacterium is 10⁻¹⁵ kg.
We are told that the mass of a hydrogen atom is 10⁻²⁷ kg.
Finally we learn that the average mass of an atom of the bacterium is ten times the mass of a hydrogen atom.
Mass of an atom of bacterium = 10 x mass of hydrogen atom
= 10 x 10⁻²⁷ kg.
= 10⁻²⁶ kg.
Thus the number of atoms in a bacterium =
=
= 10¹¹
Answer:
The answer is 200mL each amount have the same mass
Explanation:
100mL +100ML= 200mL mass in each container
Yes, you can!
Hope this helped you, brainliest much needed and appreciated! Have a wonderful day!:)
Answer:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
Explanation:
Answer:
0.99 m³
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law </em>to calculate the volume
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₁
p₁V₁ = p₂V₂T₁/T₂ Divide each side by p₁
V₁ = V₂ × p₂/p₁ × T₁/T₂
<em>Data:
</em>
p₁ = 201 kPa; V₁ = ?; T₁ = 27 °C = 300.15 K
p₂ = 2.5 kPa; V₂ = 59.3 m³; T₂ = -14 °C = 223.15 K
<em>Calculation:
</em>
V₁ = 59.3 × 2.5/201 × 300.15/223.15
V₁ = 20 × 0.0124 × 1.345
V₁ = 0.99 m³
