Answer: Scientists look for cell types, the ability to make food, number of cells in their bodies.
Explanation: Scientists look for cell types, the ability to make food, number of cells in their bodies when placing newly-discovered organisms.
1 kg =1000 g = 10³ g,
1 m = 100 cm ,
(1m)³ = (100 cm)³= (10²)³ cm³ = 10⁶ cm³ or 10⁶ mL
5,427 kg/m³ = <span>5,427 kg/ 1m³ = (5427 * 10³ g)/ 10⁶ mL=5427/10³ g/mL=
=5427/1000 g/mL = 5.427 g/mL
</span>5.427 g/mL is density of Mercury, and 1.0 g/mL is density of water.
Density of Mercury is more then density of the water, so
mercury will sink in the water.
The 15th Amendment to the Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude."
Answer:
0.06mole
Explanation:
Given parameters:
Volume of balloon = 2.5L
T = 343.5K
P = 66.7kPa; in atm gives = 0.66atm
Unknown:
Number of moles of He = ?
Solution:
To solve this problem, we use the ideal gas equation.
It is mathematically expressed as;
Pv = nRT
where p is the pressure
v is the volume
n is the number of moles
R is the gas constant
T is the temperature
0.66 x 2.5 = n x 0.082 x 343.5
n = 0.06mole
