Two hormonal methods of contraception are birth control pills and implants. The pills are taken daily or 3 weeks out of the month and typically have two major hormones that prevent ovulation. The implant is a device placed in the arm that releases hormones constantly to prevent ovulation for up to 3 to 5 years.

Answer:
1.030-0.545=0.485 grams of oxygen in compound.
Convert grams of Al and grams of O into moles:
0.545g Al x 1 mol Al/26.98g Al = 0.0202 mol Al
0.485g O x 1 mol O/16.00g O = 0.0303 mol O
Next we divide the moles of both of them by the lowest number to get simplest ratio
0.0202/0.0202 = 1 Al
0.0303/0.0202 = 1.5 O
Next we multiply all numbers until we get a whole number for each one. In this case 2 works:
Al 1 x 2 : O 1.5 x 2
and we are left with Al2O3

The answer is false.
As we grow older, our bodies break down.
This is why we need to take physical check-ups to see how our bodies are
doing. Bad health choices and lack of
exercise can slow down our metabolism and even cause illness. We need to maintain a good diet, proper
exercise and take medication to maintain our metabolism and health.
