Answer:
Venus has a very small axial tilt -- 3 degrees versus Earth's 23.5 degrees. Its dense, acidic atmosphere produces a runaway greenhouse effect that keeps the surface at around 865 degrees F year-round, which is hot enough to melt lead.When the solar system settled into its current layout about 4.5 billion years ago, Venus formed when gravity pulled swirling gas and dust together to form the second planet from the Sun. Like its fellow terrestrial planets, Venus has a central core, a rocky mantle and a solid crust.

The mass of Al metal that releases 2.4 L of hydrogen gas at STP is calculated as below
AT STP 1 mole =22.4 l
what about 22.4l =? moles
(22.4 L x 1 mole) /22.4 L= 2mole
write the reacing reaction
2Al+ 6 HCL = 2AlCl3 + 3H2
by use of mole ratio between Al to H2 which is 2 : 3 the mole Al = 1 x2/3 = 0.667 moles
mass =moles x molar mass
=0.667 mole x27 g/mol= 18 grams
An autoclave would often be used by Microbiologists. Or laboratory instructors working in the microbiological setting.
Answer:
a. 1 x 10^8
Explanation:
100 MHz = 100,000,000 Hz = 10^8 Hz
Answer:
Molarity NaOH = 0.0263M
Explanation:
Molarity Acid x Volume Acid = Molarity Base x Volume Base
12.5ml x 0.60M = 285ml x M(base)
M(base) = 12.5ml x 0.60M / 285ml = 0.0263M
