Answer:
Hi, There! I'm here to help!
Hydrogen is placed in group 1 in the modern periodic table.
This Statement Is True!
Explanation:
Hydrogen can form ionic compounds like other group I elements. Due to all of these similarities Hydrogen is placed in group I of the modern periodic table.
Answer:
64799.4 J
Explanation:
The following data were obtained from the question:
Mass (M) = 1.05 kg = 1.05 x 1000 = 1050g
Specific heat capacity (C) = 0.9211 J/g°C
Initial temperature (T1) = 23°C
Final temperature (T2) = 90°C
Change in temperature (ΔT) = T2 – T1 =
90°C – 23°C = 67°C
Heat required (Q) =....?
The heat required to increase the temperature of the kettle can b obtain as follow:
Q = MCΔT
Q = 1050 x 0.9211 x 67
Q = 64799.4 J
Therefore, 64799.4 J of heat is required to increase th temperature of the kettle from 23°C to 90°C.

Answer:
1. Chemical reactions
2.Substances
3. Properties
4. Precipitate
5. Light
6. Temperature
7. Color
8. Gas
Explanation:
Chemical reactions are known to produce new substances which have new properties. During the chemical reactions, evidences that are seen are formation of precipitate or light gel, production of gas and change in temperature and color.
Chemical reactions occur when chemical substances come together to react because those substances are compatible with each other.
