Answer:
I think false
Explanation:
It might be false because bacteria can be found on hard/soft surfaces, in our bodies, in the ground, and in the air.
When an atom shares electrons they form a covalent bond.
There are many types of acid or bases. Based on the Bronsted-Lowry definition,
* A Bronsted-Lowry acid is a proton donor
* A Bronsted-Lowry base is a proton acceptor
Take this reaction for example:
HCl(aq)+ N<span>H</span>₃(aq)→N<span>H</span>⁴⁺(aq)+C<span>l</span>⁻(aq<span>)
</span>
HCl donates a proton, so it is a Bronsted-Lowry acid. Consequently, ammonia accepts this proton, so it is the Bronsted-Lowry base.
825.5mL
To find this, use the equation 
= 
Make sure to convert all temperatures in Celsius to Kelvin by adding 273. Once you do that, multiply and divide accordingly to get the final answer of 825.5mL
Hope this helps!
Answer:
Mass = 11.16 g
Explanation:
Given data:
Mass of hydrogen = 8 g
Mass of oxygen = 10 g
Mass of water produced = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen:
Number of moles = mass / molar mass
Number of moles = 8 g/ 2 g/mol
Number of moles = 4 mol
Number of moles of oxygen:
Number of moles = mass / molar mass
Number of moles = 10 g/ 32 g/mol
Number of moles = 0.31 mol
now we will compare the moles of hydrogen and oxygen with water.
O₂ : H₂O
1 : 2
0.31 : 2/1×0.31 = 0.62
H₂ : H₂O
2 : 2
4 : 4
Number of moles of water formed by oxygen are less this it will act as limiting reactant.
Mass of water:
Mass = number of moles × molar mass
Mass = 0.62 mol × 18 g/mol
Mass = 11.16 g
