Why is a lunar eclipse happening in Image 2? A. The Moon is directly in between Earth and the sun, in a straight line.

B. The illuminated half of the Moon is facing away from Earth.

c. The Moon is far away from the sun, so the sun’s light is weaker.

D. Earth is blocking the sun’s light from hitting the Moon.

if Earth is in between the sun and the Moon in both Image 1 and Image 2, why do you think a lunar eclipse is only happening in Image 2?

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
