Hey mate
This is the answer
The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.
Plsssssss mark me as brainliest
I don’t know about 3 but I know that 4 is solid, 5 is you’ll feel the vibration first, 6 is you’ll see the lightning first because the speed of light is faster than the speed of sound and 7 is sound waves need a medium to travel and light waves don’t, sound waves are longitudinal and light waves are transverse, and sound waves are mechanical waves while light waves are electromagnetic waves
Answer:
293.1 mL.
Explanation:
- Boyle's law states that: at a constant temperature the pressure of a given mass of an ideal gas is inversely proportional to its volume.
- It can be expressed as: <em>P₁V₁ = P₂V₂,</em>
P₁ = 546.0 mm Hg, V₁ = 350.0 mL.
P₂ = 652.0 mm Hg, V₂ = ??? mL.
<em>∴ V₂ = (P₁V₁)/(P₂)</em> = (546.0 mm Hg)(350.0 mL) / (652.0 mm Hg) = <em>293.1 mL.</em>
Answer: I believe it is B
Explanation:
because it states that a chemical compound always contains exactly the same proportion of elements by mass
Electricity
fuel
friction, gears, and energy
how fast the motor spins, how long it spins, and how much fuel or electrify it is given. This is because the amount of fuel given would effect how long the motor spins thus giving out a certain amount of electricty.
