Answer:
Valence Electrons are transferred/exchanged
Answer:
pH 4
Explanation:
Firstly, we define pH as the negative logarithm to base 10 of the concentration of hydrogen ions.
Mathematically, we express this as:
pH = -log[H+]
Now let’s us calculate the concentration of hydrogen in each of the pH
For pH 4, we have:
4 = -log[H+]
[H+] = -Antilog(4)
[H+] = 0.0001M
For pH 5,
[H+] = -Antilog(5)
[H+] = 0.00001M
We can see that 0.0001 is greater than 0.00001 and thus it has a greater concentration of hydrogen ions
Answer:
0.57 water
Explanation:
To solve this problem, we need to write the reaction expression first.
The reactants are oxygen gas and hydrogen gas.
They react to give a product of water
2H₂ + O₂ → 2 H₂O
Given that;
Number of moles of hydrogen gas = 0.57moles
From the balanced reaction expression;
2 moles of hydrogen gas produces 2 moles of water
So;
0.57mole of hydrogen gas will also produce 0.57 water
Answer:
50 mm
4 ft
36 ft
250 cm
1 L
Explanation:
Centimeter to millimeter:
1 cm is equal to 10 mm.
5cm× 10 mm/1 cm
50 mm
Inches to feet conversion:
1 foot is equal to 12 inches.
48 inch × 1 feet /12 inch
4 feet
Yard to Feet conversion:
1 yard is equal to 3 feet.
12 yd × 3 ft / 1 yd
36 ft
Meter to centimeter:
One meter is equal to 100 cm.
2.5 m × 100 cm / 1m
250 cm
Milliliter to Liter:
One L is equal to 1000 mL.
1000 mL = 1 L
Answer:
false
Explanation:
Elements are pure substance. A ball of sodium will only have sodium atoms.
