Photosynthesis produces glucose and oxygen.... Respiration on the other hand would produce the other options.
Answer:
f = 0.084 s⁻¹
Explanation:
Given data:
Frequency of light = ?
Wavelength = 35.6 m
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light = 3× 10⁸ m/s
by putting values,
3× 10⁸ m/s = 35.6 m × f
f = 3× 10⁸ m/s / 35.6 m
f = 0.084 s⁻¹
Answer:
Silk worm
Explanation:
Silk worms are boiled and the silk around them is removed
Answer:
C. chromium is a metal that is less reactive than sodium.
Explanation:
Hello.
Given the options:
A. chromium is a nonmetal and therefore a good conductor of heat and electricity
.
B. chromium is a metal that is more reactive than potassium
.
C. chromium is a metal that is less reactive than sodium
.
D. chromium is a noble gas that is not reactive.
In this case, since chromium is in period 4 group VIB we infer it is a transition metal which slightly reacts with acids and poorly reacts with oxygen and other oxidizing substances. Thus, in comparison with both sodium and potassium which are highly reactive even with water as they get on fire, we can say that it is less reactive than both potassium and sodium, therefore, answer is: C. chromium is a metal that is less reactive than sodium.
Best regards.
I think that's called "Trajectory"
