Covalent bonds are between two non-metals. Hydrogen and oxygen are non-metals. Hence is is, "yes, hydrogen and oxygen are nonmetals."
For the future, you might want to look at some videos to help you! :) (Tyler DeWitt is a really good chem you-tube teacher!)
Red litmus turns blue in alkaline conditions. Alkaline can also be considered as basic. So the if the strip of litmus is red then the answer will be C.

Answer:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
Explanation:
To balance the equation, you should apply the law of conservation of mass for the equations.
The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
Hydrocarbon is burned in oxygen to produce CO₂ and H₂O.
So, the given equation is balanced as:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
that 1.0 mole of C₃H₈ is burned in 5.0 moles of O₂ to produce 3.0 moles of CO₂ and 4.0 moles of H₂O.
The no. of all atoms is the same in both of reactants and products side.
C (3), O (10), and H (8).
Answer:
2.39 moles
Explanation:
From the question given above, the following data were obtained:
Pressure (P) = 2.34 atm
Volume (V) = 25.6 L
Temperature (T) = 305 K
Number of mole (n) =?
NOTE: Gas constant (R) = 0.0821 atm.L/Kmol
The number of mole of CO₂ can be obtained by using the ideal gas equation as shown below:
PV = nRT
2.34 × 25.6 = n × 0.0821 × 305
59.904 = n × 25.0405
Divide both side by 25.0405
n = 59.904 / 25.0405
n = 2.39 moles
Thus, the number of mole of CO₂ is 2.39 moles.
