Answer:
Water can hold a lot of heat inside it and as the climate starts getting cold, the water releases the heat which heats up the climate
Due to the fact that water has a high heat capacity, its temperature has a very limited range, which causes the coastal areas close to having a similar small daily and seasonal temperature range.
What is specific heat capacity?"When the temperature of a material rises 1 K (or 1 °C), the amount of heat (J) absorbed per unit mass (kg)".
When the weather begins to grow chilly, water releases the heat it has stored inside, warming the environment.
High specific heat of the water makes it temperature resistant, and it helps the earth to maintain its temperature and helps organisms to maintain their functions at a constant temperature of the earth.
Thus, the normal temperature is necessary for maintaining the temperature of the earth and the water bodies maintain the temperature of the earth.

How many atoms are there in 7.6 moles of Iron?
Answer:
45.77 × 10²³ atoms
Explanation:
Given data:
Number of moles of iron = 7.6 mol
Number of atoms = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.

WHAT DOES THE MASS OF AN OBJECT MEASURE HURRYYYYYYYYYYYYYYYYYYYYY
Answer:
object's inertial property
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
Answer:
The mass of the object internal property, or the amount of matter it contains

What is the only nonmetal in group 14?
Answer:
Carbon is the only nonmetal element in the group
Explanation:
Carbon and silica are the non- metal which are placed in group 14.
What is non metal?
Non-metals were elements on the periodic table's right side. Gases, liquids, and solids above are all examples of non-metals. Non-metals are not as lustrous as metals and have a drab color.
The carbon family belongs to Group 14. Carbon, silicon, germanium, tin, and lead are the five members. In their uppermost energy level, each of these elements possesses four electrons. Only carbon and silicon create nonmetal bonding among the Group 14 elements and form by sharing electrons .

Sodium is going in group 1, period 3. It contains A. One valence electron in its 3rd energy shell B three valence electron in its 1st energy shell C. 11 protons, 11electrons , 11 neutrons D. 11 protons, 11 electrons and 23 neutrons
Answer:
The correct answer is option A, that is, one valence electron in its third energy shell and option C, that is, 11 electrons and 11 protons.
Explanation:
The outermost electrons and the ones that take part in the process of bonding are termed as valence electrons. The atomic number of sodium is 11, thus, it possesses 11 protons and the atoms are neutral so it suggests that sodium has 11 electrons. By electronic configuration, it can be seen that in sodium, two electrons are present in the first shell, 8 in the second, and only one electron in the third shell, that is, 2.8.1. The electron present in the third shell is the valence electron.

2 Ca + O₂ → 2 CaO
Required
a redox reaction
Solution
Redox reactions are reactions where there is a change in oxidation number
Oxidation is an increase/increase in oxidation number, while reduction is a decrease/decrease in oxidation number.
Reducing agents are substances that experience oxidation and oxidizing agent are substances that experience reduction
in the above reaction is included in a redox reaction because there is a change in oxidation number
Ca⇒Ca²⁺+ 2e⁻(for balanced equation : 2Ca⇒2Ca²⁺+4e⁻)
Oxidation ( 0 to +2)
O₂+2e⁻⇒O²⁻(for balanced equation : O₂+4e⁻⇒2O²⁻)
Reduction (0 to -2)

Potasyum-40 küçük atom numaralı doğal radyoaktif birkaç element izotopundan biridir ve doğada K izotopları içerisindeki bolluk yüzdesi %0,012'dir. 1,65 mg K/mL içeren bir bardak sütü içtiğiniz zaman kaç tane 40K atomu yutmuş olursunuz? (1 Bardak süt 225 mL, K: 39,10 g/mol)
Answer:
6.707 × 10¹⁷
Explanation:
From the information given:
40 ^ K kütlesi = sütteki K kütlesi × 40 ^ K / 100 kütle yüzdesi
nerede;
sütteki K kütlesi = 1.65 mg of K/mL × 225 mL = 371.25 mg of K
∴
40 ^ K kütlesi = 371.25 × 0.012/100
40 ^ K kütlesi = 0,04455 mg = 4.455 × 10⁻⁵ grams
40 ^ K mol sayısı = 40 ^ K kütlesi / molar kütle
= 4.455 × 10⁻⁵/40
= 1.11375 × 10⁻⁶
Son olarak, 40 ^ K = mol × Avogadro sayısı atomları
= 1.11375 × 10⁻⁶ × 6.022 × 10^23
= 6.707 × 10¹⁷
