QUËSTIONS :- what are the difference between ionic bond and covalent bond?
IONIC BONDS :- THEY R BONDS WHICH R FORMED DUE TO THE COMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
COVALENT BONDS :- THEY R THE BONDS WHICH R FORMED DUE TO INCOMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
IONIC BONDS R MORE STRONGER.
So in your question that ask to calculate the Ph result of the resulting solution if 26 ml of 0.260 M HCI(aq) is added to the following substance. The the result are the following:
A. The result is pH= 14-pOH
B. There are 10ml of 0.26m HCL excees in this reaction so the answer is log(H)+
Answer is: <span>A. supplies the body with oxygen and nutrients, and picks up carbon dioxide wastes.
</span>The blood<span> transports:
</span>1) oxygen<span> from the </span>lungs<span> to the </span>cells<span> of the body.
</span><span>2) </span>carbon(IV) oxide <span>from metabolism to the lungs, where it is exhaled.
3) </span>nutrients<span>, transports </span>hormones<span> and removes waste products.</span>
The correct answer are
identify the positive ion and charge
balance the charges
identify the negative ion and charge
Answer:
Option c → 8:1
Explanation:
This is the reaction:
C₅H₁₂ + 8O₂ → 10CO₂ + 6H₂O
1 mol of pentane needs 8 moles of oxygen to be combusted and this combustion produces 10 mol of carbon dioxide and 6 moles of water.
To determine the ratio, look the stoichiometry.
For every 8 moles of oxygen, I need 1 mole of pentane gas.
