3) Warm Temperatures and High pressures
Explanation:
This is the typical characteristic of southern air masses moving north
Answer:
The atomic mass of element is 65.5 amu.
Explanation:
Given data:
Abundance of X-63 = 50.000%
Atomic mass of X-63 = 63.00 amu
Atomic mass of X-68 = 68.00 amu
Atomic mass of element = ?
Solution:
Abundance of X-68 = 100-50 = 50%
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (50×63)+(50×68) /100
Average atomic mass = 3150 + 3400 / 100
Average atomic mass = 6550 / 100
Average atomic mass = 65.5 amu.
The atomic mass of element is 65.5 amu.
Rock and sand are non-living. All organisms are living.
Answer:
Explanation:
(a) Balanced reaction of gallium with oxygen is as follows:
(b) 
Multiply the carbon dioxide by 6 to balance carbon as follows:
After that multiply H2O by 7 to balance hydrogen as follows:
Finally balance oxygen by multiplying O2 by 19/2. Therefore, balanced reaction is as follows:
(c) 
first balance calcium, by multiply 
by 3 as follows:
After that balance phosphorous by multiplying 
by 2 as follows:
Finally balance Na by multiplying NaCl by 6. Therefore, balance reaction is as follows:
