Explanation:
H2O, what is the maximum amount of H2O which could be formed from 10.9 g of H2 and 16.03 g ofO2? Answer in units of g. ... 0.500 mol O2 x 2 mol H2O / 1 mol O2 x 18 g H2O/mol H2O = answer in ..
Answer:
Explanation:
The atomic radius of elements are used to estimate the sizes of elements. The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
To solve this problem we will obtain the atomic radius values of the given elements from a standard atomic radius table;
Si 111 pm
P 98 pm
Cl 79 pm
S 87pm
pm = picometer
We see that chlorine has the least atomic radius
In scientific notation 1.5 square micrometers is 1.5e-12 square meters.
Answer:
It will take 140.76 seconds to swim 0.150 miles.
Explanation:
Distance covered by man by swimming for t time= d
d = 1500.0 miles
t = 14 minutes + 34.56 seconds
1 min = 60 seconds
t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds
Speed of the man while swimming = S = 
If the man swims 0.150 miles with the same speed ,then the time taken by him be T.
0.150 miles = 0.150 × 1609.34 m = 241.401 m
(1 mile= 1609.34 meters)
T = 140.76 seconds
It will take 140.76 seconds to swim 0.150 miles.
Answer: The purpose is to analyze the speed of planets around a central star.
