Answer:
Explanation:
molar mass of any subtance in 1 litre water gives 1N solution
for NaOH molar mass =40 g
40g --- 1000ml ---1N
Xg---- 150 ----0.02
X= 40*150*0.02/1000*1 =0.12 g
Answer:
Competition occurs when <em>(A) two or more organisms need the same resource.</em>
Explanation:
I dont think it could be (B), (C) or (D) because those don't really make sense.
Answer:
Newton's first law of motion describes inertia. According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force
Answer:
Each cell contributes power of 14.7 Watts.
Explanation:
Total power generated by alkali furl cells = 14,800 Watts
Total number of fuel cells = 1,008
Power produced by one fuel cell = x
Total power generated = 
Each cell contributes power of 14.7 Watts.
Explanation:
molarity = no. of moles of solute/solution in litres
molarity =0.202/7.98
=0.025 M
