Answer:
The answer is : Yes
Explanation:
because it 12:00 and the storm is moving at 25km/hr and it 75 km away that means in three hours the storm would hit your town so at 3:00 the storm would hit at your at ends at 2:00 so yes you would get home before he storm hit.
Answer:
It would be the third answer.
Explanation:
This is because over the next few minutes, the heat would radiate away from the atoms in the metal plate and the atoms around the plate would absorb this radiation.
20 g of contains ions of
<h3>What is Mole?</h3>
A mole is a unit to measure an amount of any substance which contains as many elementary particles as there in 12 g of Carbon 12.
A mole contains particles and this fixed number is called Avogadro’s number.
No. of moles is given by,
where m = Given mass in grams
M = Molar mass
Here,
No. of moles of = = 0.132 moles
No. of molecules of = 0.132 x 6.022 x = 7.94 x
No. of molecules of = no. of ions of = no of ions of
Thus, no. of ions in 20 g of is 7.94 x

Correct answer is option E. <span>It is a redox reaction in which Zn is oxidized at the anode, and V is reduced at the cathode.
Reason:
In above reaction, the oxidation state of VO3- is +5, while that of VO2 is +4. Thus there is reduction of V from +5 to +4
In case of Zn, oxidation state of Zn is increased from 0 to +2, Thus process is referred as oxidation. </span>
Answer:
Draw the curved arrows showing a proton transfer reaction, and draw the products of that proton transfer. Do not include the Li counterion, and lone pairs are not required in the products and the question is hsown below:
Explanation:
The proton from water is abstracted by butyl carbanion and hydroxide ion is formed from water.
The reaction is shown below in the attachment.
