Answer:
1. Yes
2. No
2. Yes
4. Yes
5. Yes
Step-by-step explanation:
The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)
Segment FG is 4 cm while segment DE is 6 cm so they are not congruent
As shown on the figure both segment OR and segment OS is 2 in. long
Angle 2 and angle 4 are congruent
Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
