<span>Yes. If you put solutions containing the same concentration table salt, glucose and starch in different bags and place the bags in water (i.e., 0M) solution, then the bag with salt will contain more water after 15 minutes than the bag with glucose, which will contain more than the bag with starch.</span>
Answer:
Q = 2.415kj
Explanation:
Q = Mc∆temperature
c = 0.46j/g°c = 0.46kj/kg°c
mass = 150g = 0.15kg
∆temperature = 60 - 25 = 35°c
Q = 0.15 X 0.46 X 35 = 2.415kj
Q = 2.415kj
Oxygen exhibits only one mode of vibration, on the other hand, methane has four and carbon dioxide has three modes of vibration. The vibration of oxygen is only a single stretching movement, while both the molecules of methane and carbon dioxide can change greatly, and can range from bending to stretching in almost any direction or pattern.
142 kg in grams:
1 kg ---------- 1000 g
142 kg -------- ?
142 x 1000 / 1 => 142000 g
Atomic mass Cu = 63.54 a.m.u
Therefore:
63.54 g ------------ 6.02x10²³ atoms
142000 g --------- ??
142000 x ( 6.02x10²³) / 63.54 =
8.54.10²⁸ / 63.54 => 1.34.10²⁷ atoms of Cu
Explanation:
it's true that Lysosomes break down old and worn out cell parts....
