45,000 written in scientific notation would be 4.5×10⁴.
The number first has to be written so that there's only one number to the left of the decimal point.
4.5000
The decimal point would have to be moved 4 places to the right for the decimal to become 45,000 again. Therefore, the exponent on the 10 would be positive 4.
The answer is B I had took that last year
The answer is B. It will grow towards the hole in the box because the plant will try and get as close to the sunlight as possible which is called phototropism.
The answer is
<span>Fe3+ + e- Fe2+ = 0.77 V</span>
The solution for this problem is:
Look for the moles of NaOH which is 0.0385 L x 0.150 M = 0.00578
H3PO4 + 3 NaOH = Na3PO4 + 3 H2O
moles H3PO4 = 0.00578 / 3 = 0.00193
M of H3PO4 = 0.00193 mol / 0.0150 L= 0.128 is the molality we are looking for in this problem.
