Answer:

تتشكل الروابط التساهمية ، التي تربط الذرات داخل جزيء فردي معًا ، من خلال مشاركة الإلكترونات في المدارات الذرية الخارجية. يعتبر توزيع الإلكترونات المشتركة وكذلك غير المشتركة في المدارات الخارجية محددًا رئيسيًا للشكل ثلاثي الأبعاد والتفاعل الكيميائي للجزيئات. على سبيل المثال ، كما تعلمنا في الفصل 3 ، فإن شكل البروتينات أمر بالغ الأهمية لوظيفتها وتفاعلها مع الجزيئات الصغيرة. في هذا القسم ، نناقش الخصائص المهمة للروابط التساهمية ووصف بنية الكربوهيدرات لتوضيح كيف تحدد هندسة الروابط شكل الجزيئات البيولوجية الصغيرة.

If a position time graph has a constant slope, what can you infer about the<br> acceleration?
gogolik [260]

Answer:

Acceleration is zero.

Explanation:

The slope of a position time graph gives the velocity of the body.

If the slope is constant means the velocity is constant.

Now, acceleration is the measure of the change in velocity of a body over a given time interval.

So, the acceleration of a body is directly proportional to the change in velocity of the body.

If there is no change in velocity, this means that the acceleration of the body is zero.

Here, the slope is a constant implying that the velocity is a constant. So, there is no change in velocity. This implies that the acceleration is zero for the body in the given time interval.

Thus, if a position time graph has a constant slope, one can infer that the  acceleration is zero.

What is the percent composition of Br in CuBr3?
tekilochka [14]

Answer:

about 79% (79.04369332 to be exact)

Explanation:

Percent composition=(Molar mass of element x amount of it)/Molar mass of compound x 100

Br= 3 x 79.9/303.25 x100=79.04369332

In the reaction H2SO4 + 2 NaOH -&gt; Na2SO4 + 2H2O, an equivalence point occurs when 29.43 mL of 0.1973 M NaOH is added to a 32.
Tamiku [17]
            moles NaOH = c · V = 0.1973 mmol/mL · 29.43 mL = 5.806539 mmol
            moles H2SO4 = 5.806539 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 2.9032695 mmol
Hence
            [H2SO4]= n/V = 2.9032695 mmol / 32.42 mL = 0.08955 M
The answer to this question is  [H2SO4] = 0.08955 M
